Out of all of our units so far, I have found this unit to be the most interesting. The ability of the immune system to hunt down and destroy bacteria and suppress unkillable viruses is something that I find to be amazing.

AP Science Practices
  • SP1:The student can use representations and models to communicate scientific phenomena and solve scientific problems.
  • SP2: The student can use mathematics appropriately.
  • SP3: The student can engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course.
  • SP4: The student can plan and implement data collection strategies appropriate to a particular scientific question.
  • SP5: The student can perform data analysis and evaluation of evidence.
  • SP6: The student can work with scientific explanations and theories.
  • SP7: The student is able to connect and relate knowledge across various scales, concepts and representations in and across domains.

  • Populations are subject to natural selection which selects more successful phenotypes over time.
  • Biological systems are affected by disruption to dynamic homeostasis.
  • Organisms have a variety of chemical defences against infections that affect dynamic homeostasis.
  • Viral replication results in genetic variation, which can introduce genetic variation into the hosts.
